Being pedantic, that a story is only something that must somehow self-destruct from all relays after 24 hours, then nostr is not the place for it, unless you write to a private relay you control and delete it yourself, and even then, I imagine it can be broadcast to other relays once seen.

I'm suggesting a different approach, that stories are a set of notes that you are pinning to your profile with a replaceable event, like a mute or relay list. Not the same, but similar.
